• Portable audio players (MP3, etc.)
• CD and DVD players/recorders
• MiniDisc recorders
• Audio interfaces
• Home theatre systems

Features:

• 24-bit stereo CODEC
• Integrated headphone driver
• Multi-bit sigma-delta ADCs and DACs
• Sampling rates up to 96kHz
• Low power consumption
• Analog input and output gain control
• I2S interface
• Flexible digital audio interface
• 48-pin LQFP package

Benefits:

• High-fidelity audio performance for demanding audio applications.
• Reduced component count and board space due to integrated functionality.
• Low power consumption for extended battery life in portable devices.
• Easy integration with digital audio systems through the I2S interface.
• Flexible audio processing capabilities through programmable gain control.

Additional Details:

The WM8772EFT utilizes multi-bit sigma-delta ADCs and DACs to achieve high resolution and low distortion audio conversion. The integrated headphone driver can directly drive headphones with low impedance. The I2S interface allows for seamless connection to digital audio processors and other audio devices. The device features independent gain control for both analog inputs and outputs, allowing for fine-tuning of audio levels. It is important to refer to the datasheet for specific electrical characteristics, application circuits, and programming guidelines.
